Content delivery to a mobile device from a content service

ABSTRACT

Systems and methods for delivering digital content to a mobile device from a digital content provider are disclosed. Digital content is selected using a selection interface on the mobile device. The selected content is then transferred to a computing device by the digital content provider and subsequently transferred to the mobile device by the computing device. In some embodiments, the digital content is reformatted before being transferred to the mobile device. The digital content may be streamed from the computer system to the mobile device. A service provider of a network through which the mobile device connects to the digital content provider may bill a user of the mobile device on behalf of the digital content provider. The digital content provider may bill the user of the mobile device using a Premium SMS service.

BACKGROUND

1. Field of the Invention

The present invention generally relates to the field of digital content distribution to mobile devices.

2. Description of the Background Art

A user purchasing digital content from a content provider for download to a mobile device conventionally engages in a prerequisite financial transaction using the mobile device. Following the transactions, the user then downloads the digital content from the content provider directly to the mobile device. In some instances, the purchased digital content is too large to be stored on the mobile device or is formatted for a display screen much larger than that provided by the mobile device. In other instances, the purchased digital content is too large to be downloaded from the content provider to the mobile device in a reasonable period of time due to bandwidth limitations over a mobile network.

Purchased digital content may also require a Digital Rights Management (DRM) enabled application not supported by or available at the mobile device. The purchased digital content can thus only be downloaded to a computing device supported by the DRM enabled application such as a desktop or laptop personal computer. Further, backing up the digital content from the mobile device to a computer readable storage medium or a computing device may be inconvenient or impractical. Therefore, digital content that is purchased and downloaded directly to a mobile device may be lost if the mobile device becomes damaged or lost.

SUMMARY

Systems and methods are provided to select and purchase digital content from a content provider and download the selected digital content to a mobile device. The systems and methods overcome problems in the prior art related to the selected digital content being too large for download to the mobile device. The systems and methods may utilize an additional computing device to reformat the selected digital content to reduce file size, display resolution, and/or bit rate of a representation of the selected digital content to be downloaded to the mobile device. The systems and methods also overcome problems in the prior art related to DRM authorization of the selected digital content not being supported by the mobile device. The systems and methods may utilize an additional computing device to provide DRM authorization prior to transferring a representation of the selected digital content to the mobile device. The systems and methods additionally overcome problems in the prior art related to backing up digital content downloaded to the mobile device. The systems and methods may utilize an additional computing device to maintain a backup of digital content for which a representation of the selected digital content is transferred to the mobile device.

A system for delivery of digital content to a mobile device comprises a server hosting digital content and a computing device communicatively coupled to the server and the mobile device via at least one network. The server is configured to transfer digital content to the computing device via a network connection. The digital content is transferred in response to a user selection at the mobile device. The computing device is configured to receive the digital content from the server via the network connection, store the digital content in a computer readable storage medium, and transfer a representation of the digital content to the mobile device via a mobile network connection. The representation of the digital content is transferred in response to the user selection at the mobile device.

A method for delivery of digital content to a mobile device comprises receiving digital content from a server at a computing device in response to a user selection at a mobile device. The computing device includes a computer readable storage medium. The method additionally includes storing the digital content on the computer readable storage medium at the computing device. The method further includes transferring a representation of the digital content from the computing device to the mobile device in response to the user selection at the mobile device.

A method of billing for digital content purchased from a digital content provider using a mobile device comprises identifying a user of the mobile device, identifying the digital content purchased by the user of the mobile device, determining a price of the digital content purchased by the user of the mobile device, and submitting information representative of the purchase to a service provider of a mobile network associated with the mobile device. The invoice comprises the identity of the user of the mobile device and the price of the digital content purchased by the user of the mobile device. The user is billed by the service provider of the network on behalf of the digital content provider.

A computer readable storage medium has stored thereon a program. The program is executable by a processor for performing a method for delivery of data to a mobile device. The method comprises listing data available for transfer to the mobile device, receiving a user selection of data to transfer to the mobile device, optionally reformatting a representation of the data to transfer to the mobile device, and transferring the representation of the data to the mobile device.

DETAILED DESCRIPTION

FIG. 1 is an illustration of a content distribution and billing system for mobile devices. The content distribution and billing system includes a content provider 110 (which may include a server), a mobile device 120, a personal computing device 130, and optional central server 140. All of the aforementioned may be interconnected through network 150. The content provider 110, the personal computing device 130, and the central server 140 may include a computer processor, a memory, a computer readable data storage medium, a network interface, and input/output devices such as a video display, keyboard, mouse, touchpad, touch screen, and so forth.

The personal computing device 130 may be owned or controlled by an entity other than an entity that operates the network 150, the optional central server 140, and/or the content provider 110. Alternatively, the personal computing device 130 may be owned or controlled by an entity that owns or controls any of the above. The personal computing device 130 may be owned or controlled by a user of the mobile device 120.

In various embodiments, the content provider 110 may include one or more service or processing nodes configured to perform one or more functions of the content provider 110. The content provider 110 may also include a proxy for another service or processing node configured to perform one or more functions of the content provider 110. Each of the one or more nodes of the content provider 110 may independently operate and connect to the network 150. The optional central server 140 and the personal computing device 130 may be configured in a similar fashion.

The mobile device 120 may be configured to communicate between a user and other mobile devices as well as other computing devices over the network 150. The mobile device 120 may include a cellular telephone, a smart phone, a personal digital assistant (PDA), a wireless e-mail device, a handheld computer, and the like. The mobile device 120 may include communications components (not shown) such as a radio frequency (RF) antenna, an optical transceiver (e.g., infrared), modulator/demodulator, and codec circuitry configured to interface to the network 150. The mobile device 120 may include input/output components such as a display, a keypad, a keyboard, a touchpad, a touch screen, a microphone, a speaker, headphones, headphone jack, a Bluetooth interface, a speech recognition application, e-mail application, web browser application, MP3 music player, and the like.

A server at the content provider 110 may be operated to provide digital content 113 to one or more customers over the network 150. The one or more customers may be users of the mobile device 120 or personal computing device 130. Digital content 113 at content provider 110 may be stored on a computer readable data storage medium such as a magnetic hard drive, optical disk, CD-ROM, DVD-ROM, HD-DVD disk, Blu-ray disk, magnetic tape, flash memory, and so forth. The digital content 113 may include digital audio data files, mobile device ring-tones, e-book data files, picture data files, video data files, e-mail data files, voice message data files, Short Message Service (SMS) data files, document files, and software applications. The content provider 110 provides representations (e.g., copies) of the digital content 113 over the network 150.

The content provider 110 may also include billing application 117. The content provider 110 may be configured to bill a user for representations of the digital content 113 purchased and/or received from the content service provider 110. The content provider 110 may maintain an account record corresponding to a user, who may be a customer of the content provider 110.

The account record may include an identifying element such as a user's customer account number, user ID or user name, password, mobile device electronic serial number (ESN), mobile device telephone number, landline telephone number, credit card number, and so forth. The account record may also include a content provider service plan, connection information for the user's personal computing device 130, credit balance, purchased balance, payment history, mobile network service provider account information, and so forth. The content provider 110 may use the account record to determine whether to offer the user digital content 113, which one or more items of digital content 113 to make available to the user, and what prices to charge the user for those available items of digital content 113.

The network 150 is inclusive of a wireless network such as a cellular telephone network, a WiFi network, a WiMax network, and the like which may be operated by a mobile network service provider. The network 150 may also include a wired network such as an Internet network. The wired network may further include wired connections such as Ethernet connections, plain old telephone service (POTS) connections, digital subscriber line (DSL) connections, community access television (CATV) connections, fiber optic connections, and coaxial cable connections.

The content provider 110, mobile device 120, personal computing device 130, and/or the optional central server 140 may communicate with one another over the network 150 via one or more wireless and/or wired networks. In one example, the mobile device 120 communicates with the content provider 110 via a combination of a wireless cellular telephone network and a wired Internet network. In another example, the content service provider 110 communicates with the personal computing device 130 via a combination of a wired Internet network and a wireless WiFi network. In a still further example, the mobile device 120 communicates with the personal computing device 130 via a combination of a cellular telephone network, a wired Internet network, and a wireless WiFi network.

A user may initiate a connection between the mobile device 120 and the content provider 110 via the network 150. The connection may be established using a web browser running on the mobile device 120 and communicating with a web server running on the content provider 110. Alternatively, the connection may be established using an applet or client software application running on the mobile device 120. The applet or client software application, in turn, communicates with a server software application running on the content provider 110. A content selection interface 127 provided on the mobile device 120 may be configured to inform the user of one or more available items of digital content 113 available on the content provider 110.

The content provider 110 and/or the content selection interface 127 may selectively enumerate available items of the digital content 113. These enumerations may be based upon various criteria such as user preferences, desired digital content genre or category, and user account balance with the content provider. The content selection interface 127 may list the available items of digital content 113 in the form of a textual list, collection of graphical icons, or other means of presentation. After the user selects an available item from the list, the content selection interface 127, through mobile device 120, transmits the selection to the content provider 110 via the network 150.

The content provider 110 may be configured to require the user of the mobile device 120 to authorize a purchase of the selection through the billing application 117. The content provider 110 may use identifying information transmitted by the user and/or the mobile device 120 to the content provider 110 to authorize the purchase, for example, by comparing the identifying information (like that disclosed above) with the account record. The billing application 117 may store a user's credit card number on file and allow the user to authorize a charge on the credit card by transmitting a password from the mobile device 120 to the content provider 110 or via an SMS message.

The mobile network service provider may operate an optional central server 140 including a central billing application 142 configured to facilitate billing the user for purchases of digital content 113 from the content provider 110. The billing application 117 may interface with the central billing application 142 to bill the user via the mobile network service provider on behalf of the content provider.

The billing application 117 may transmit a Premium SMS message or a Reverse Billed SMS message to the mobile device 120 requesting the user to authorize the purchase of the selection. After the user authorizes a charge for the purchase, the content provider bills the user via the mobile network service provider on behalf of the content provider. In this manner, the mobile network service provider may include a charge from the content provider on the user's mobile network service provider bill. The user may then pay the mobile network service provider directly for the charge as part of the user's mobile network service provider bill payment. The mobile network service provider then pays the content provider for the charge, which may include a transaction fee.

The content provider 110 is configured to transfer a representation (e.g., transmit a copy) of the selected digital content 113 to the personal computing device 130 associated with the user of the mobile device 120. The representation may include a single selected format of the selected digital content 113 or multiple formats of the selected digital content 113. For example, the representation may include a digital music file in an MP3 format and another representation of the same digital music file in an AAC format. Alternatively, the representation may include multiple representations of a digital music file encoded at different bit rates. For example, one representation may be optimized for quality at a higher bit rate and have a larger file size, while another representation is optimized to conserve bandwidth at a lower bit rate and have a smaller file size. The representation optimized for quality may be intended for transfer to the mobile device 120 in a single “chunk”, while the representation optimized to conserve bandwidth may be intended to transfer to the mobile device 120 via streaming media.

The personal computing device 130 includes a content acquisition application 138 configured to receive the representation of the selected digital content 113 from the content provider 110. The content acquisition application 138 is configured to store the representation of the selected digital content 113 to a downloaded content store 132. The downloaded content store 132 may be stored on a computer readable data storage medium such as a hard drive, an optical disk, a CD-ROM, a DVD-ROM, a Blu-ray disk, an HD-DVD disk, a flash memory, a dynamic random access memory, or a static random access memory.

The personal computing device 130 also includes content management software 136. The content management software 136 may be configured to manage digital content stored in downloaded content store 132, content acquisition application 138, content reformatting application 135, and content transfer application 134. Various content management functions may be performed by the content management software 136 or by other software modules in conjunction with the content management software 136.

The personal computing device 130 may be configured to reformat downloaded digital content using the content reformatting application 135. The content reformatting application 135 may decode, encode, transcode, and resample digital content.

The content reformatting application 135 may initiate reformatting of the downloaded content in response to a command issued by another software module at the personal computing device 130, the content provider 110, or by the mobile device 120. Reformatting may also occur automatically according to user preferences stored at the personal computing device 130. The content reformatting application 135 may include copying a file stored in the downloaded content store 132 while changing a file format from one format to another, or while changing a bit rate or resolution such that the copy has a different bit rate or resolution than the original.

In one example, the content reformatting application 135 reformats an MPEG-2 encoded video file to a 3GP encoded video file by copying the MPEG-2 encoded video file and saving the copied video file in the downloaded content store 132 as a 3GP encoded video file. In a second example, the content reformatting application 135 reformats an AVI encoded video file having a resolution of 720 by 480 pixels to an AVI encoded video file having a resolution of 360 by 240 pixels. In another example, the content reformatting application 135 reformats an MPEG-4 encoded video file having a frame rate of approximately 30 frames per second (fps) to an MPEG-4 encoded video file having a frame rate of approximately 15 fps. By further example, the content reformatting application 135 reformats an MP3 encoded audio file having a bit rate of 192 kilobits per second (kbps) to an MP3 encoded audio file having a bit rate of 128 kbps.

The content reformatting application 135 may also be configured to reformat the downloaded content based upon a command received from the central server 140 or available bandwidth between the personal computing device 130 and the mobile device 120. The content reformatting application 135 may also reformat the downloaded content based upon a factor dependent on the personal computing device 130 such as available storage space at the personal computing device 130, a factor dependent on the mobile device 120, a user-selectable preference, or a preset preference. The factor dependent on the mobile device 120 may include supported codecs (e.g., MP3 and WMA), bit rates (i.e., bits per second), sampling rates (i.e., samples per second), sample resolutions (i.e., bits per sample), and video frame rates (i.e., frames per second). The factor dependent on the mobile device 120 may also include a memory size, free available memory, a screen size, and a screen resolution.

As an example, the downloaded content may be reformatted to more compact file sizes when free available memory at the mobile device 120 is low, and larger file sizes when free available memory at the mobile device 120 is high. As another example, the downloaded content may be reformatted to a lower resolution screen size when the mobile device 120 is a cellular telephone than when the mobile device 120 is a PDA. The downloaded content may be reformatted to a resolution somewhat larger (finer) than the screen size resolution to allow the downloaded content to be zoomed and cropped to a reasonable degree at the mobile device 120.

The content transfer application 134 is configured to transfer a representation of the downloaded content to the mobile device 120. The content transfer application 134 may transfer the representation of the downloaded content in response to a command received from the content provider 110, from the mobile device 120, from a user of the personal computing device 130, and/or from the content management software 136. Alternatively, the content transfer application 134 may transfer the representation of the downloaded content automatically according to a user preference setting.

The content transfer application 134 may transfer the representation of the downloaded content to the mobile device 120 as a single file sent in one contiguous “chunk” by a protocol such as File Transfer Protocol (FTP). Alternatively, the content transfer application 134 may transfer the representation of the downloaded content to the mobile device 120 using a streaming media protocol such as User Datagram Protocol (UDP), Real-time Streaming Protocol (RTSP), Real-time Transport Protocol (RTP), Real-time Transport Control Protocol (RTCP), Transmission Control Protocol (TCP), or other protocols suitable for streaming digital media over networks. Transferring the representation using the streaming media protocol may be referred to as “streaming” the representation.

The content reformatting application 135 may be configured to reformat the downloaded content based upon a characteristic of the downloaded content such as file size, file type, access history, or probability of being requested by the mobile device 120. The format and/or resolution used for reformatting may be chosen based upon a historical pattern of formats or resolutions previously requested by the mobile device 120. Similarly, a historical record of available bandwidth between the personal computing device 130 and the mobile device 120 may be used.

In an example, downloaded content that is identified as having been frequently accessed is reformatted in advance of being requested by the mobile device 120. Likewise, in another example, downloaded content such as an audio book may be reformatted at a lower bit rate than downloaded content such as a music file, which requires a higher bit rate.

Mobile device 120 includes a content reception interface 125 configured to receive the representation of the downloaded content transferred by the personal computing device 130. The content reception interface 125 may be further configured to store the representation of the downloaded content to a mobile content store 122 for later retrieval and use on the mobile device 120. The mobile content store 122 may include a computer-readable data storage medium such as a flash memory, a hard drive, a dynamic random access memory, a static random access memory, and the like.

The content reception interface 125 may alternatively be configured to buffer the representation of the downloaded content for more immediate playback on the mobile device 120.

Central server 140 may be configured to act as an intermediary between the personal computing device 130 and the mobile device 120. The central server 140 may include a central content transfer application 144 configured to relay data between the personal computing device 130 and the mobile device 120. In this configuration, rather than transferring a representation of the downloaded content from the downloaded content store 132 to the mobile device 120, the content transfer application 134 transfers a representation of the downloaded content to the central server 140 via the network 150. The central content transfer application 144 receives the representation of the downloaded content from the personal computing device 130, optionally reformats the representation of the downloaded content using a central content reformatting application 146, and transfers the optionally reformatted representation of the downloaded content to the mobile device 120.

The personal computing device 130 or the central server 140 may be configured to monitor and measure available bandwidth in a connection to the mobile device 120 over the network 150. The available bandwidth may be determined by monitoring data throughput between the personal computing device 130 and/or the central server 140 and the mobile device 120. The bandwidth may be measured continuously during data transmission such that when a bandwidth measurement value is desired, a separate bandwidth measurement does not need to be made.

Alternatively, the available bandwidth may be determined based on a network service plan that includes policies that enforce a limit on available bandwidth to some pre-determined value. For example, a basic network service plan may include a lower bit per second bandwidth for streaming media or a lower limit on kilobits of data transfer per billing period than an expanded network service plan. The available bandwidth may also be determined based upon a difference between the service plan policy limit and a measure of the service already utilized during a billing period.

The available bandwidth may be used to determine a format, bit rate, or resolution of the representation of digital content transferred to the mobile device 120. In an example, the personal computing device 130 measures throughput of data transmitted to the mobile device 120 to be 100 kbps. The personal computing device 130 then uses the content reformatting application 135 to resample a selected MP3 file in the downloaded content store 132 from 192 kbps to 96 kbps prior to streaming the MP3 file to the mobile device 120.

The personal computing device 130 may be configured to transfer a representation of any data stored on the personal computing device 130. For example, the personal computing device 130 may allow the mobile device 120 to access data available at the personal computing device 130 such as the downloaded content or other data that was not downloaded from the digital content provider 110, including data at a computer readable storage medium coupled to the personal computing device 130. The mobile device 120 and the computing device 130 may be configured to communicate with each other in a manner similar to that described elsewhere herein with reference to the mobile device 120 selecting and downloading digital content from the digital content provider 110.

The personal computing device 130 may be configured to receive an authentication token from the mobile device 120 to authorize the mobile device 120 prior to providing data and/or services to the mobile device 120. The authentication token may be an identifying element associated with the user of the mobile device 120 or the mobile device 120 itself.

The personal computing device 130 may be configured to serve as a proxy for the mobile device 120. As such, the personal computing device 130 may allow the mobile device 120 to access network services and servers such as the content provider 110 via a proxy application. The proxy application may be configured such that a connection between the mobile device 120 and the content provider 110 via the proxy application appears to be a direct connection. Alternatively, the proxy application may be configured to enable the mobile device 120 to control a direct connection between the personal computing device 130 and the content provider 110. Additionally, the proxy application may enable the mobile device 120 to access any data available via a connection from the personal computing device 130 to other computing devices and servers over the network 150. The mobile device 120 and the proxy application may be configured to communicate with each other in a manner similar to that described elsewhere herein with reference to the mobile device 120 selecting and downloading digital content from the digital content provider 110.

FIG. 2 is a flowchart depicting a method 200 for content delivery to a mobile device. In this exemplary method 200, a server (110) hosting digital content transfers selected digital content to a computing device (130) where it is stored and optionally reformatted. A representation of the digital content is then transferred to the mobile device.

In step 210, digital content on the server is selected by a user for download. The server hosting the digital content may be operated by a content provider and communicate with the mobile device over a network. The mobile device may be akin to mobile device 120 and its various functionality as discussed above.

In step 220, an optional financial transaction between a content provider and a customer is conducted. The customer is a user of the mobile device and the content provider is associated with the server hosting the digital content. The financial transaction may include an agreement between the customer and the content provider that the customer will pay the content provider, optionally via a third party, for purchased digital content. The content provider will then provide the customer with the purchased digital content.

In an exemplary method of conducting the financial transaction, the content provider bills the customer directly. The content provider may have the customer's credit card on file as part of the customer's account record. The content provider may use SMS-based authorization or a software application installed on the mobile device and configured to conduct the financial transaction between the user of the mobile device and the content provider. The software application may include security features such as encryption in conducting the financial transaction. A unique authentication token may be provided by the mobile device to validate the financial transaction. Another exemplary method of conducting the financial transaction is illustrated in FIG. 3.

In step 230, the computing device receives digital content from the server hosting the digital content. The digital content may be transferred by the content provider over the network. The digital content may be transferred in response to a user selection as in step 210.

In step 240, the digital content is stored at the computing device. The digital content may be stored on a computer readable storage medium at or coupled to the computing device. The digital content may be stored in an original form as received from the content provider. The digital content may be stored at the computing device indefinitely, whether or not a representation of the digital content is transferred to the mobile device. If the mobile device is lost or damaged, the digital content may not be lost.

In optional step 250, the digital content is reformatted. The computing device may reformat the digital content by copying the stored digital content and saving the copied digital content on the computer readable storage medium in a different format. Reformatting may include filtering, transcoding, refactoring, and/or resampling. The reformatting may be performed in response to a request received from the mobile device such as a request to download content in a format different from that of the stored digital content.

The computing device may reformat the digital content in one or more different formats automatically upon receiving the digital content from the content provider. The one or more formats that the digital content is reformatted into may be based upon a variety of factors including user settings, content genre, original content format, DRM authorization, available free storage space on a computer readable storage medium coupled with the computing device, and available bandwidth of a data channel between the mobile device and the computing device. Other factors related to the mobile device include screen size, screen resolution, memory size, available free memory, processing power, supported codecs, supported bit rate, supported sampling rate, supported sample resolution, supported video frame rate, and the like. By reformatting the digital content automatically, in advance of being requested to be downloaded to the mobile device, a latency between a request to download the reformatted digital content to the mobile device and completion of the requested download may be reduced. A central server communicatively coupled with the computing device and the mobile device over the network may receive the digital content from the computing device and reformat the digital content in preparation to forward the reformatted digital content to the mobile device.

In step 260, a representation of the digital content is transferred to the mobile device. The computing device may transfer the representation of the digital content over the network. In some embodiments, the central server may transfer the representation of the digital content to the mobile device.

The mobile device and/or the computing device may be configured to automatically and/or periodically transfer a representation of digital content from the computing device to the mobile device. The digital content of which a representation is transferred may be chosen randomly, according to user settings such as a playlist, according to a history of prior transfers indicating the frequency with which various digital content has been transferred in the past, the elapsed time since a particular item of digital content has been transferred, a characteristic of recently downloaded digital content, a location of the mobile device, an analysis of web sites recently visited by the user of the mobile device, and the like.

The digital content received from the server hosting the digital content may require a storage capacity exceeding the available memory or storage space on the mobile device. The mobile device and/or the computing device may be configured to transfer a representation of a portion of the digital content rather than the entire received digital content. The user of the mobile device may be queried to select one or more portions of the digital content to transfer. The user of the mobile device may be queried regarding whether to transfer the one or more portions of the digital content via contiguous “chunks” and/or streaming media. An algorithm may be utilized to automatically select the one or more portions of the digital content to transfer based upon factors as described elsewhere herein.

The mobile device may be configured to selectively replace existing digital content already stored at the mobile device with a representation of the digital content received from the server hosting the digital content by deleting the selected stored digital content to free storage space prior to transferring the representation of the digital content received from the server. One or more of a variety of algorithms may be provided to select the stored digital content to delete. The algorithm may consider one or more of the following factors in making the selection: available storage space, frequency of access or playback, elapsed time since last access or playback, user-specified priority, or user-selection at a deletion prompt. Additional factors the algorithm may consider include logical grouping or genre of digital content such as music style, artist, album, program series, and so forth. Alternatively, the mobile device may be configured to receive the digital content by streaming media if the mobile device has insufficient available memory or storage space to receive the digital content via contiguous “chunks”.

The mobile device and/or the computing device may be configured to establish a lifetime for a representation of digital content to remain on the mobile device prior to automatically being deleted. The lifetime may be useful to provide a means for digital content to be automatically deleted to free memory on the mobile device. The lifetime may be a characteristic of a perishable or disposable representation of digital content. The lifetime may also be set according to a requirement of the content provider, for example to enforce a rental of digital content as opposed to a purchase of digital content.

FIG. 3 is a flowchart depicting a billing method 300 for content delivery to a mobile device (120). In this billing method 300, a user of the mobile device is identified by a content provider (110), digital content purchased by the user is identified, a price of the digital content is determined, and the user is billed on behalf of the content provider by a mobile network service provider associated with the mobile device.

In step 310, the user of the mobile device is identified. The content provider may maintain an account record corresponding to the user. The user may be a customer of the content provider. The content provider may identify the user by receiving at least one identifying element from the mobile device and matching the at least one identifying element with a customer account record.

In step 320, the digital content to be purchased by the user is identified. The digital content to be purchased may be identified by the user selecting digital content to purchase from a list or enumeration of digital content offered for purchase to the user by the content provider. The content provider may use the account record to determine whether to offer the user digital content and what digital content to offer to the user. The user may select digital content to purchase from the digital content offered to the user for purchase by the content provider.

In step 330, a price of digital content purchased is determined.

Alternatively, the user may be instructed to send an SMS message to a specified number, such as a 5 digit Short Code, to confirm the agreement to purchase the digital content.

In step 350, the financial transaction is validated. Validating the financial transaction includes the user identified in step 310 executing an agreement to purchase the digital content selected in step 320 for the price determined in step 330. The financial transaction may be validated by receiving a purchase confirmation in response to the Premium SMS message sent in step 340. Validating the financial transaction may include the content provider receiving an identifying element from the user, the identifying element being used as a unique authentication token to validate the financial transaction.

In step 360, information representative of the purchase is submitted to the mobile network service provider. The information may include an identity of the user of the mobile device, a price of the digital content purchased by the user of the mobile device, a title of the digital content purchased by the user, a date of the purchase, and so forth. The mobile network service provider may use the purchase information to bill the user on behalf of the content provider. A charge for the purchase may be included on a mobile network service provider bill sent to the user. The user may pay the mobile network service provider for the charge. The mobile network service provider may pay the content provider at least a portion of the amount paid by the user, the mobile network service provider optionally subtracting a transaction fee or the like from the amount paid by the user for the charge before paying the content provider.
